Methods:The present study was aimed at investigating a well-known antioxidant, Forskolin for its therapeutic role in streptozotocin-induced diabetic nephropathy in rats.The effect of Forskolin was investigated by assessing the key markers of kidney function along with the morphological changes in the kidney.Further, the effect of Forskolin on the formation of AGEs and AR inhibition and lipid peroxidation was compared with that of a standard AR inhibitor, fidarestat. Results:The results revealed that Coleus forskohlii methanolic extract and Forskolin significantly (P<0.05)decreased the blood glucose levels, urinary protein excretion, serum creatinine and blood urea nitrogen in diabetic rats.Administration of Forskolin to diabetic rats decreased kidney lipid peroxides and nitrate levels along with decrease in AGEs formation.In addition, Forskolin was found to inhibit kidney AR activity. Conclusion:Thus, the results obtained in this study underline the potential of Forskolin as a possible therapeutic agent against diabetic complications such as nephropathy.Read More
